L-seryl-tRNASec selenium transferase

L-seryl-tRNASec selenium transferase

In enzymology, a L-seryl-tRNASec selenium transferase (EC number|2.9.1.1) is an enzyme that catalyzes the chemical reaction

:L-seryl-tRNASec + selenophosphate ightleftharpoons L-selenocysteinyl-tRNASec + phosphate

Thus, the two substrates of this enzyme are L-seryl-tRNASec and selenophosphate, whereas its two products are L-selenocysteinyl-tRNASec and phosphate.

This enzyme belongs to the family of transferases, specifically those transferring selenium-containing groups selenotransferases. The systematic name of this enzyme class is selenophosphate:L-seryl-tRNASec selenium transferase. Other names in common use include L-selenocysteinyl-tRNASel synthase, L-selenocysteinyl-tRNASec synthase selenocysteine synthase, cysteinyl-tRNASec-selenium transferase, and cysteinyl-tRNASec-selenium transferase. This enzyme participates in selenoamino acid metabolism. It employs one cofactor, pyridoxal phosphate.
